It seems very likely that there are even predictions that say the price of bitcoin will be $1.2k nobody will know, so ahead of Christmas and New Year there will be massive sales that will make bitcoin prices continue to decline, there is no sign of increasing this year can only expect big changes towards a more positive next year.
I think that NY or Christmas will not influence BTC price. Everybody (I mean individuals) who wanted to sell already did it or are doing it right now. Now some institutional players are capitulating. So it not depends on holidays. This sell off will continue for a week. But yes, price will go lower. 2 800 is my prediction to the December 31.
